RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description zhenfeng wang 2014-02-19 10:13:51 UTC 
+++ This bug was initially created as a clone of Bug #1066894 +++

Description of problem:
Implement for libvirt guest's xml that it should report error or left only one uniqure security label while there have two or more same Security label in the guest's xml

Version-Release number of selected component (if applicable):
kernel-3.10.0-88.el7.x86_64
qemu-kvm-rhev-1.5.3-47.el7.x86_64
libvirt-1.1.1-23.el7.x86_64
libselinux-2.2.2-6.el7.x86_64
selinux-policy-3.12.1-125.el7.noarch
How reproducible:
100%

Steps
1.Prepare a normal guest
# virsh list --all
 Id    Name                           State
----------------------------------------------------
 -     rhel75                         shut off

2.Edit the guest's xml, Add 5 or more same security label, save the guest's xml,
it didn't report error while edit the guest's xml, also it generate many same
seclabel in the guest's xml , i think we can do some implement for this issue
#virsh edit rhel75
--
<seclabel type='dynamic' model='selinux'/>
<seclabel type='dynamic' model='selinux'/>
<seclabel type='dynamic' model='selinux'/>
<seclabel type='dynamic' model='selinux'/>
<seclabel type='dynamic' model='selinux'/>
--

#virsh dumpxml rhel75|grep seclabel
  <seclabel type='dynamic' model='selinux' relabel='yes'/>
  <seclabel type='dynamic' model='selinux' relabel='yes'/>
  <seclabel type='dynamic' model='selinux' relabel='yes'/>
  <seclabel type='dynamic' model='selinux' relabel='yes'/>
  <seclabel type='dynamic' model='selinux' relabel='yes'/>

3.Start the guest, check the guest's xml, we can see only one seclabel work,
other seclabel didn't work
#virsh start rhel75
# virsh dumpxml rhel75 |grep seclabel -A 3
  <seclabel type='dynamic' model='selinux' relabel='yes'>
    <label>system_u:system_r:svirt_t:s0:c12,c756</label>
    <imagelabel>system_u:object_r:svirt_image_t:s0:c12,c756</imagelabel>
  </seclabel>
  <seclabel type='dynamic' model='selinux' relabel='yes'/>
  <seclabel type='dynamic' model='selinux' relabel='yes'/>
  <seclabel type='dynamic' model='selinux' relabel='yes'/>
  <seclabel type='dynamic' model='selinux' relabel='yes'/>
